What is the Datastore VMFS version being used on your datastores? You have to upgrade this separately from the hosts. Do do this normally you need to migrate all data off the datastore. Delete the datastore and recreate it using the current VMFS version. If you have gone through several upgrades without doing this your datastores are likely on a very old version

Is this something that needs done on the SAN?

I upgraded both Datastores from the host and it was successful and shows them running as VMFS-5...

You can access all VMDK files and all your VMs are good to go? If there are no VMs present, just create one quickly and see if it works.

One more thing, do you have any other volumes that are unmounted in the storage view? That is another cause of this warning.

The most important thing is that the datastore(s) you are using for this host are operational, if they are, then this warning is an false positive.

Yes - live

Yes - All VMs on both datastore

Screenshot of datastores showing VMFS5 and Live / normal

Screenshot from Host (other host is identical - 2x iSCSI paths to the SAN datastores, and 1x local for SD card. Could the local card be the issue? All that is on it is ESXi - no VMs. And there are no actions available for it..)
